First results of measurements of charged-particle fluxes on the GRANAT spacecraft
Abstract
The KS-18-M instrument for charged-particle measurements on the Granat spacecraft is described. Data obtained from Dec. 2, 1989 to July 31, 1990 are examined. Particular attention is given to the proton event of March 19, 1990, which exhibited a remarkable feature: a repeated sign inversion of the proton anisotropy with a period of about two hours.
